DOOR-CHECK.

SPECIFICATION forming part of Letters Patent No. 230,422, dated July 27, 1880,

Application filed July 16, 1879. I

To all whom it may concern:

Be it known that I, SAMUEL D. KELLEY, of Somerville, State of Massachusetts, have in vented a Combined Door Stop and Catch, of which the following is a specification.

The object of my invention is to combine in a compact self-contained form an elastic stop for arresting the movement of a door when it is swung open and a catch which shall retain the door in place when it is thus arrested by the elastic stop; and the invention consists in a frame or stock, preferably of c'ast-iron, made in a single piece, said frame consisting of a Fig. l

standard or base'with a short arm to hold a buffer or elastic stop and a long hollow arm, within which is pivoted a catch-lever having a knob at its inner end, said lever being actu-,

ated by a spring seated in a recess in the frame, to secure the door in position when it has been swung open and brought in contact with the buffer or stop.

Figure l is a plan view of my invention as secured to the base-board of a room, such board, as also a door, being shown in horizontal section. Fig. 2 is a side elevation of my invention as viewed in the direction of the arrow in Fig. 1. Fig. 8 is an end elevation as viewed from the right in Fig. 1. Fig. 4 is a transverse section taken on line 0 D, Fig. 2, and through the pivot of the catch-lever. Fig. 5 is a plan view of the catch-lever. Fig. 6 is a detached vertical section taken on lineAB,

Fig. 7 is a plan view, showing a modification of my invention, a portion of the frame being represented as broken away to show the coiled spring that actuates the catch-lever.

In these views, E represents the base-board, F the door, and G a section of the floor. The frame or body of my stop and catch is formed with the base a, by which to secure it in place by screws passingathrough the base, as shown in Figs. 1, 2, 3, 7. From this base a standard, b, rises and "diverges into arms 0 e, the elastic stop orbuifer (I being secured in an axial hole in arm 0, and the catch-lever f being pivoted at tin the arm 6. This lever is formed at its outer end with a catch or hook, g, to engage and hold the door, while upon its opposite end and edge is formed the actuating-knob h, by pressing upon which the lever is vibrated upon its pivot and the catch is released from the door.

A coiled sprin g, j, seated in a cavity in standard b, and acting against lever f, serves to engage catch 9 with door F.

The slotted arm 6 is made long enough to protect the outward extremity of the catchlever f, leaving only the hook g projecting above, so that the door, when opening, impinges against it. (SeeFigs. 1 and 2.) The knob his fixed to the inward end of the catchleverf, as shown, and the implement thus constructed is deemed the best for compactness and protection of the operating parts.

In Fig. 7 base a is shown as secured to floor G, and the plane of the arms 0 e as parallel to that of the base. but at right angles to the axis of standard b, the catch-lever f in this figure being shown as shortened, and the catch 9 as engaging in a seat in the edge of the door, instead ofinclosing it, as in the other figures.

It will be apparent that by the pressure of the foo; upon knob h the catch g will be actuated and the door released.

The frame or body in which the buffer cl and catch-leverf are held may be varied in its form and details to best adapt it to the various positions and uses required.

I am aware of certain patented devices showing a door-check having an elastic stop and a pivoted catch-lever provided with a spring to actuate'the same; but the advantages of my compact construction, having the parts protected, as shown, are deemed quite important in the practical use of the implement. Therefore I claim as my invention- A door-check in which the base and arms are made in a single piece, the short arm to hold an elastic stopand the long arm being hollow and having the catch-lever pivoted. therein, said lever having a knob at its inner end and being provided with a spring which is seated in a recess in the frame, as herein specified.

I SAMUEL D. KEELEY.
